JOHN B. HADAWAY, OF SWAIVIPSCCTT, MASSACHUSETTS, ASSIGN'OR, BY MESNEASSIGN- MENTS, 'IO UNITED SHOE MACHINERY CORPORATION, OF PATERSON, NEWJERSEY,

A CORPORATION OF NEW JERSEY.

WELT-BEATIN G MACHINE.

To all whom it may concern:

Be it known that I, JOHN B. HADAWAY, a citizen of the United States,residing at Swampscott, in the county of Essex and State ofMassachusetts, have invented certain new and useful Improvements inWelt-Beating Machines; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as willena'ble others skilled in the art to which it appertains to make and usethe same.

This invention relates to welt beating ma.- chines for beating out thewelt of a lasted shoe and, more particularly to machines of this classin which the welt beating means has an intermittent gripping engagementwith the welt. Certain features of the invention, however, are notlimited to Welt beating machines in which the welt beating means hasthis particular mode of operation but may be embodied with advantage inother welt beating machines.

Welt beating machines of the type at present in common commercialuseare-provided with a welt support and with a welt beating hammer which isvibrated with great rapidity to beat out the welt as it is advancedacross the upper surface 0 fthe welt support.

In such machines the welt is fed between the strokes of the hammer whenthe hammer is disengaged from the welt. Young or inexperienced operatorsare very frequently employed to operate these machines and the welt isoften advanced so rapidly through the machine that the operatlon is notsufficiently performed. It is desirable that the welt should be beatenout more or less at all points so that it will lie fiat in substantiallythe plane of the insole, and the welt is often slighted by the operatorat certain points particularly along the sides of the shoe so that it isnot in proper condition. when the outsole is applied thereto. 'Toobviate this difiiculty it has been proposed to provide machines of thistype with a feed mechanism arranged to advance the welt a predetermineduniform distance between the strokes of the hammer. It is not desirable,however,

that the welt should be fed at the same speed at all points sincecertain portions thereof, such as the toe, ordinarily require a moreextended beating than other parts. i

: One object of the present invention is to Specification of LettersPatent.

Application filed April 2, 1915. Serial No. 18,692.

produce a welt beating machine of the type havlng welt beating meansacting to grip the welt intermittently in which it will be impossiblefor the operator to advance the welt more rapidly than a predeterminedspeed and upon which the welt beating operation may be performed in aneflicient and reliable manner.

Other objects of the invention are to improve the construction and modeof operation of welt beating machines and to produce amachine upon whichthe welt beating operation may be performed with the exerclse of a lessdegree of skill and care on the part of the operator than isreguired inthe operation of machines heretofore produced.

With this object in view, one feature of the invention contemplates theprovision in a welt beating machine having welt beatmg mean's acting togrip the welt intermittently of means for limiting the speed at whichthe welt may be fed through the machine arranged to allow the feed to becontrolled by the operator within the limiting speed. This provisionprevents the welt from being slighted or left unbeaten at any point andat the same time allows the operator to control the feed so as tosubject certam portions of the welt to a more extended beating actionthan other portions thereof.

Another feature of the invention contemplates the provision, incombination with means for limiting the speed at Which the welt may befed through the machine, of means for varying the limiting speed duringthe operation of the machine.

In the present embodiment of the invention means is provided for varyingthe pressureof the welt beating means on the welt during the operationof the machine so that certain portions of the welt may be subjected toa heavler beating action than other portions thereof and another featureof the invention contemplates the provision of a connection between thepressure varying means and the mechanism for controlling the speedlimiting means arranged to cause a decrease in the limiting speed uponincreasing the pressure of the welt beating means on the welt. Thisprovision insures a more extended beating of the welt at the refractoryportions thereof where the pressure of the welt beating means isincreased.

Other features of the invention consist of certain novel and improvedconstructions, arrangements and combinations hereinafter described andparticularly pointed out in 5, the claims, the advantages of which willbe i elevationof the machine; Fig. 2 is a view in front elevation of themachine with the welt support in lowered position illustrating the partsin the positions which they as sume at one point in the operation of themachine; Fig. 3 is a view similar to Fig. 2 illustrating certain of theparts in different positions; Fig. 4 is a view in front elevation of themachine illustrating the parts in the positions which they assume atsubstantially the same point in the operation as illustrated in Fig. 3,but with the welt support in raised position; and Fig. 5 is a detailview of the treadle mechanism for elevating the welt support andcontrolllng the operation of the slashing knife.

. The welt beating machine illustrated in the drawings has thesannegeneral construction and mode of operation as the welt beating machineshown and described in the patent to Hadaway, Serial No. 875,171, datedDecember 31, 1907. The machine is provided with a welt support indicatedat 2 which is shaped to enter the crease between the upper and welt of alasted shoe s0 as to support the welt upon its upper surface and with avibratory welt beating ham- 'mer indicated at 4 arranged to deliverblows on the welt as it is advanced across the upper surface of the weltsupport. The hammer is secured to the lower end of a hammer rod 6mounted to slide in suitable guides in the forward end of the hammerlever 8. To cushion the blows delivered by the hammer upon the welt acoiled spring 10 mounted in a cylindrical chamber in the forward end ofthe hammer lever surrounds the hammer rod and engages at its upper endthe upper face of the chamber in the hammer lever and at its lower end ashoulder on the hammer rod. The downward movement of the hammer in thehammer lever is limited by a clamping nut 12 threaded upon the upper endof the hammer rod. The hammer lever 8 is mounted to oscillate upon avshort shaft 14 supported on the frame of the machine and is rapidlyoscillated to vibrate the hammer by means of an eccentric fixed to themain shaft 16 of the machine and operating within an eccentric block 18mounted in the forked rear end of the hammer lever.

The machine is provided with a welt slashing knife indicated at 20which, except as hereinafter described, has substantially the sameconstruction, arrangement and mode of operation as the welt slashingknife of the machine illustrated and described in the Hadaway patentreferred to above. The welt slashing knife is secured to the forward endof the reciprocatory slide 22 the rear end of which is connected with anoscillatory lever 24 pivoted at 26 and provided with a cam roll 28engaging a cam groove 30 in a cam disk 32 mounted to turn upon arearwardly extending shaft 34 fixed in the frame of the machine. Themain shaft 16 of the machine carries a worm meshing with a Worm wheel 36mounted on the rearwardly extending shaft 34 alongside the cam disk 32and a sliding clutch pin 38 mounted in the cam disk 32 and arranged tobe moved into and out of clutching engagement with the worm wheel 36, ispro dvided to connect the cam disk with the worm wheel at certain.timesso that the cam disk may be actuated to operate the welt slashing knife.The action of the clutch pin is controlled by a wedge 40 mounted uponthe extremity of a lever 42, pivoted 'upon the shaft 44 and normallyheld in elevated position by. a tension spring 46 to maintain the clutchpin 38 disengaged from the worm wheel 36. The lever 42 may be depressedto allow the clutch pin to be actuated by the spring 48 to engage theworm wheel 36 and thereby connect the cam disk with the worm wheel bymeans of a treadle I connected with the lever by a treadle rod 50.

In order that the pressure of the welt beating hammer on the welt may bevaried at different points in the welt, the welt support is mounted inthe machine so that it may be adjusted vertically. To this end the weltsupport is mounted upon the forwardly extending arm of a hanger 52 whichis pivoted upon the shaft 14 of the hammer lever. To support the hanger52 an arm 54 is fixed to a stud 56 mounted in hearings in the hanger 52and engages at its rear end the curved face 58 of a support 60adjustably pivoted on the shaft 44. The lower 'end of the support 60 issupported by means of an adjustable abutment screw 62 threaded into thesupport 60 and engaging at its lower end an abutment 64 on the frame.The support 60 is adjusted so that the lower portion of the curved face58 thereof is nearer the axis about which the arm 54 swings than theupper portion of said face. With this construction the forwardlyextending arm of the hanger 52 will be lifted to elevate the worksupport by swinging the arm 54 downwardly about its pivot 56. Tomaintain the arm 54 normally in elevated position so that the worksupport is normally lowered, a spring 66 is coiled about the shaft 56,one end of said spring being fast to the. shaft and the other engaging apin 68 projecting from the hanger 52. To enable the operator to depressthe arm 54 to elevate the welt support, the arm is connected by atreadle rod 70 with a suitable treadle.

The distance which the welt may be advanced between the strokes of thehammer is limited positively to limit the speed at which the welt may befed through the machine by means of a feed limiting foot 72 arranged toengage the upper surface of the welt. This foot 72 is pivoted by a pin74 to the laterally extending arm of a rocking frame 76 mounted on theshaft 78 supported in the upwardly extending arm 80 of thehanger 52.During each cycle of operations of the machine the foot 72 is depressedinto engagement with the welt before the hammer is lifted from the weltas shown in Figs. 3 and 4 and is held in engagement with the weltbetween the strokes of the hammer. After the hammer has again engagedthe welt the foot is lifted from the welt as shown in Fig. 2. Thesemovements are imparted to the foot 72 by suitable actuating mechanismconnected with the rocking frame 76. It will be noted that with thismode of operationof the hammer and thefoot 72, the welt is at all timesengaged either by the foot or the hammer. Limiting stops are provided tolimit the swinging movement of the foot 72 along the line of feed andthereby to limit the distance which the welt may be advanced between thestrokes of the ham I mer, the foot being engaged with the rear stop whenit initially engages the welt and being swung over against the forwardstop by the feed movement of the Welt as the welt is advanced betweenthe strokes of the hammer. The frame 76 is actuated to depress the feedlimiting foot 72 into engagement with the welt by means of a spring 82coiled about the shaft 78, one end of which engages the arm 80 of thehanger 52 and the other end is made fast in a bore in the frame 76. Therocking frame 76 is actuated to lift the feed limiting foot from thewelt in timed 'relation to the movements of the hammer during each cycleof operation by mechanism comprising a bar or link 88 connected with alaterally extending arm 90 on the frame 76 by means of a pin 92 engagingin a slot 94 in the link. The lower end of the link 88 is pivotallyconnected at 96 with the arm 98 of a bell-crank lever pivoted on theshaft 44. The other arm 100 of thisbellcrank lever is slotted to receivea block 102 mounted. upon a pin 104 carried on the end of an arm 106fixed to the shaft 14 upon which the hammer lever is mounted. The

hammer lever is also fixed to this shaft so that the shaft is rocked bythe oscillating movements of the hammer lever. Through the connectionsdescribed suitable movements are imparted from the hammer lever shaft tothe rocking frame 76 to lift the feed limiting foot from the welt intimed relation to the movements of the hammer as above described. Thepin and slotconnee tion is provided between the link 88 and the arm 90of the frame 76 to allow for lost motion between these parts as thehammer lever contiues its movement after the feed limiting foot 72 hasbeen lowered into engagement with the work. The frame 76 is mounted uponthe hanger 52 which carries the welt support so that the forward end ofthe frame upon which thefeed limiting foot is mounted is raised andlowered with thewelt support. The parts of the mechanism for lifting thefeed limiting foot are arranged so that the center of the shaft 14 andthe center of the pivotal connection 96 are substantially in line withthe 'point of connection of the upper end of the link 88 with the arm90. With this construction the swinging of the hanger 52 about the shaft14 to raise and lower the welt "support will produce substantialy noangular movement of the frame 76 on the shaft 78 so that the feedlimiting foot 72 is raised and lowered substantially the same distanceas the welt support.

As above stated, in order to limit the distance which the welt may befed while the hammer is disengaged from the welt, limit ing stops areprovided for limiting the swinging movement of the foot 72. In theconstruction illustrated the rear stop indicated at 108 is secured uponthe forward end of the hammer lever by means of a screw 110 and limitsthe swinging movement of the foot 72 in a direction opposite to thedirection of feed. The foot 72 when it is lifted from the welt isengaged with the rear stop 108 by a spring 112 mounted in a suitablebore in the frame 76 and engaging an arm 114 formed on the foot 72. Theswinging movement of the foot 72 in a forward direction is limited bymeans of a stop shoulder 116 formed on the welt beating hammer 4. Withthis construction as the feed limiting foot 72 is depressed. intoengagement with the welt it is held against the rear stop 108 by thespring 112 and its position in the direction of feed at the time atwhich it engages the welt is determined by this stop. As the hammer isdisengaged from the welt the welt is advanced along the upper surface ofthe welt support until the foot 72 engages the forward stop 116 formedon the hammer, thereby limiting the advance of the welt. As the hammeris again engaged with the welt the foot 72 is lifted from the welt andis then swung rearwardly into engagement with thestop 108 by the actionof the spring 112. It will be noted that the distance which the work maybe fed between the strokes of the hammer is determined by the positionof the foot 72 in the direction of feed at the time at which it firstengages the welt and that the more advanced in the direction of feed isthe initial work engaging position of the foot, the shorter will be thedistance which the work may be fed between the strokes of the hammer.

' An important feature of the above described feed limiting mechanism isthat its construction and mode of operation is such that the operatormay control the speed at which the welt is advanced over the uppersurface of the welt support within the predetermined speed limit. Thisenables the operator to advance the welt rapidly up to the predeterminedspeed limit when operating upon portions of the welt which require arelatively slight beating out and to retard the feed when operating uponthose por tions which require a more extended beating to cause them tolie flat in the planeof the insole.

As has been stated above, it is desirable when operating upon certainportions of the welt which are particularly refractory, not only toincrease the pressure of the welt beating hammer upon the welt, but alsoto diminish the speed at which the welt is. ad vanced between the weltsupport and the hammer so that the welt will be subjected to a heavierand more extended beating action. This is particularly true whenoperating about the toe of the shoe where the curve in the shape of thewelt as it extends about the toe tends to draw the outer edge of thewelt inwardly so that the welt before'being beaten has a warped crosssection. In order to cause the initial work engaging position of thefeed limiting foot 72 to be advanced in the direction of feed to shortenthe distance which the welt may be fed between the strokes of the hammeras the welt support is lifted to increase the pressure of the weltbeating hammer upon the welt, the foot 1s formed with a stop engagingface 118. mclined as shown in Figs. 2, '3 and 4: which engage acorrespondingly inclined face on the rear stop 108. The mechanism forraising and lowering the feed limiting foot 72 is constructed andarranged to engage the foot with the work at the same point in the movement of the hammer lever regardless of the vertical position'of the weltsupport. Dur ing each cycle of operation of the machlne starting at apoint when the hammer is en gaged with the welt and the feed limitlngfoot 72 is lifted, as shown in Fig. 2, as the hammer levermoves in a'direction to-lift the forward end of the lever the frame 76 is actuatedby the spring'82 to depress the feed limiting foot 72 into engagementwith the work, the pin 92 being held against the up per end of thejslotat until the feed limiting foot engages the welt which occurs before thehammer is lifted from the welt. During upper end of the slot 94, whichoccurs after the hammer has been brought into engage ment with the work.As above. explained, the connections between the rocking frame and thebell-crank lever 98100,are arranged so that changes in the verticalposition of the hanger 52 do not affect the angular position of theframe 76 on the shaft 7 8. It will, therefore, be seen that the forwardend of the hammer lever upon which stop 108 is mounted occupies the sameabsolute vertical position at the time that the feed limiting footfirstengages the work, whether the. welt support is in raised or inloweredposition. This may perhaps be better understood by assuming thatthe machine is stationary with the parts in the positionswhich theyoccupy when the feed limiting foot is first brought into engagement withthe work as shown in Fig. 3 and that the work supportis then raised tothe position shown in Fig. 4. It should be considered that at the timewhen the feed limiting foot is brought initially into engagement withthe work the pin 92 still engages the upper end of the slot 94 and thatthe link 88 is just about to be lifted to disengage the upper end of theslot'from said pin. If, therefore, the parts of the machine arestationary in the positions shown in Fig. 3 and the work support israised to the position shown in Fig. 4 the feed limiting foot will bestill engaged with the welt and the pin 92 will remain in engagementwith the upper end of the slot 94. This is due to the fact that theframe 7 6 is mounted upon the hanger 52 so that it swings about theshaft 14 to liftthe forward end of the frame with the hanger and thatthe connections between the frame 76 and the. actuating bell crank98100, are arranged so that the swinging of the hanger 52 to lift thewelt support does not affect the angular position of the frame 76,- thefoot being lifted substantially the same distance as the welt support.Fig. 4, therefore, represents the positions of the p'artsof the machinewhen the welt support is raised and the feed limiting foot has beenjust-brought initially into enga ement with the work. As shown in Fig.4, the stop 108 occupies a lower position relative to the inclined face118 of the feed limiting foot at the time that the foot initiallyengages the work when the welt support is raised than when the weltsupportis lowered as shown in Fig; 3. Because of the inclination of thestop engaging face'118 of the feed limiting foot, the initial workengaging position, of

nected with thetreadle rods50. and 170' so 50 .the arms of a bracket128. The treadle rod "50. is threaded at its lower. end into a yoke .resondingly decreased.

11 order that the welt slashing knife may be moved vertically with thewelt. support sothat the knife will at all times be in position to actupon the wvelt as it lies on the upper surface of the welt support, theknife slide 22 is mounted in a suitable guide 120 in the hanger 52 andis held insaid guide by a retaining plate 122. With this constructionthe knife slide swings about the shaft 14: with the hanger 52 and theknife is raised and lowered with the welt support.

Separate treadles may be provided for connection with the treadle rodsand 70 to throw the welt slashing. knife into and out of operation and.to raise andlower the Welt" support independently. In ,the preferredconstruction, however, a single treadleis provided for connection withboth of these treadle rods sothat the knife is thrown into operation asthe welt sup-port is raised to increasethe pressure of the welt beatingI hammer on the welt. In the operation of machines of this type theweltslashing knife is ordinarilythrown" into operation only at the toeof the shoe and it is often desirable to increase the pressure of thewvelt beating means on the welt at portionsrthereof other than the toewithout throwing the knife into operation. construction illustrated thetreadle mechanismis constructediand arranged and conthatiupon thedepression of-the treadlethe knife is thrown into operation only afterthe welt-support has been raised to a predetermined .position' or "aftera=.,predetermined pressure of thewelt beating hammer on the welt isreached In the construction shown the treadle rod is connected-atitslower end: with a forwardly extending arm 124 fixedto a shaft126:mounted in bearings in 130 which embraces a second arm'132 'fixed tothe shaft 126, the-yokecarrymg a pm 134 which engages in a slot 136 inthe arm132.

A treadle 138 is fixedto the endof the shaft the treadle to be depressedto increase the pressure of the hammeron the? welt up to a"predetermined amount without throwing the 'welt slashing knife intooperation. When To-secure these: resultsi'n the the treadle is depressedthe arm 54, during the first part of the downward movement of thetreadle is swung downwardly to raise the Welt support and therebyincrease the pressure of the hammer on the welt.
